Definitions

  • This invention relates to a method and apparatus for separating a mixture by absorption.
  • absorption used herein refers to the phenomenon of retaining the components of a fluid on a solid regardless of the retaining mechanism, such as by adsorption, absorption, sorption, combination, ion exchange or the like. More particularly, the present invention relates to a method and apparatus for separating, by column chromatography, a solution containing two or more components into at least two fractions, i.e. a fraction rich in a component susceptible to adsorption by an adsorbent and a fraction enriched with a component which is hard to be adsorbed by an adsorbent.
  • the separation of mixtures by adsorption using various types of adsorbents has been known and widely applied industrially.
  • the simplest adsorption separator is a single column packed with adsorbents.
  • a starting solution containing both a component which is susceptible to adsorption by adsorbents and a component which is difficult to adsorb is first fed from the top of the column followed by feeding a desorbent.
  • Typical in the procedure using such column there are first discharged from the bottom a solution enriched with the hard-to-adsorb component, then a solution rich in both the hard-to-adsorb component and the easy-to-adsorb component, and finally a solution rich in the easy-to-adsorb component.
  • the solution containing the two components which is discharged at the intermediate stage of the procedure is recycled to the top of the column after being mixed with the starting solution.
  • This separation procedure can be conducted using a simple apparatus, and it is simple in operation, but the efficiency of separation is poor.
  • the procedure generally requires large quantities of desorbents, so that the concentration of the hard-to-adsorb component or the easy-to-adsorb component in a solution obtained as a product becomes diluted.
  • Japanese Laid-open Patent Application No. 53-149870 des- cribes a method in which fractions other than a product are directly recycled to the top of a column without use of any storage tank. In this method, however, the product fractions are withdrawn only from the bottom of the column. A modification is also described in which two columns are combined and fractions useful as product are withdrawn from the bottom of the respective columns. In either method, two fractions are recycled every cycle of the operation.
  • a method for efficiently separating, into the respective components, two types of components in a starting fluid i.e. at least one component which is susceptible or easy to adsorb by an adsorbent and at least one component which is hard to adsorb
  • the method comprising, in this order, the first step of feeding the starting fluid to an intermediate portion of a packed bed of an adsorption separator, in which the adsorbent-packed bed is connected with fluid passages at the front and rear ends thereof to allow the fluid to be recycled, while withdrawing a fluid which is rich in either of the components downstream of the feed port, the second step of stopping the feed of fluid to and the withdrawal of fluid from the separator and moving the fluid left in the separator in the downward direction, and the third step of feeding a desorbent fluid to the separator simul- taneously with the withdrawal of a fluid rich in either of the components from downstream of the desorbent-feed port, the withdrawal of the fluid from the separator being conducted from at least two
  • an adsorption separator for suitably carrying out the above method, the separator comprising three packed sections to 3 in which an adsorbent is packed and which are connected in series, the front end of the first packed section being connected with the rear end of the third packed section through a fluid passage so that a fluid is capable of being circulated through the respective packed sections, at least one pump mounted in the circulating system, an inlet port for a starting fluid which is located between the rear end of the second packed section and the front end of the third section, a port for introducing a desorbent fluid into the separator which port is located at an intermediate point at
  • the separation of sub- stances is conducted by the use of an apparatus provided with a bed packed with an adsorbent.
  • the packed bed is connected through a fluid passage at its front and rear ends and is provided with at least two fluid feed ports in stream direction and also with at least two fluid with- drawal ports, respectively.
  • the packed bed is divided into three sections by means of these fluid feed and withdrawal ports. In other word, the packed bed is divided into three sections in its stream direction and the fluid feed ports and/or the fluid withdrawal ports are provided between the respective sections.
  • Each section may be further divided into sub-sections.
  • sub-sections they are generally provided with fluid feed ports and/or fluid withdrawal ports between them.
  • At least one circulating pump to circulate the fluid through the separator.
  • the ; fluid is moved in one direction, that is in only a downward direction.
  • the first step is to feed the starting fluid from one of the fluid feed ports into one section of the apparatus.
  • the fed starting fluid is moved downwards through the bed, upon which the respective components contained in the starting fluid are adsorbed on an adsorbent depending on ! their degrees of affinity for the adsorbent, with the result that a dense adsorption band is formed in the downward direction from the feed port.
  • the fluid present in the bed downstream of the feed port is moved in a more downward direction by the action of a fresh starting fluid.
  • the adsorption band of at least one component of the starting fluid which is present downward of the feed port is desorbed, and the desorbed component-containing fluid is withdrawn from a fluid withdrawal port provided between one section and the next section.
  • the amount of the withdrawn solution is made equal to the feed of the starting fluid.
  • the feed of the starting fluid reaches a predetermined amount, it is stopped.
  • the amount of the starting fluid by one operation cycle is usually less than that left in the section to which the starting fluid is fed.
  • the feed of the fluid to the bed and the withdrawal from the bed are stopped, after which the circulation pump is operated to move the fluid in the bed toward the downward direction.
  • the movement involves an adsorption-desorption phenomenon which takes place between ; the adsorbent and the respective components in the starting, fluid. Accordingly, a component or components which are hard to adsorb move at greater speed whereas a component or components which are easy to adsorb move at slower speed, so that the adsorption bands of the hard-to-adsorb components and the easy-to-adsorb components are gradually but distinctly separated from each other. The degree of separation is dependent on the difference in adsorptivity of ! the respective components towards the adsorbent used and the distance of movement.
  • the fluid is passed through the circulating system and if the operating time of the circulating pump is too long, the tip of the adsorption band of the hard-to-adsorb components moving at greater speed reaches the rear end of the ad- sorption band of the easy-to-adsorb components moving at slower speed so that both adsorption bands overlap each other. Accordingly, when both adsorption bands separate from each other, the circulation pump is stopped.
  • a desorbent fluid is fed into the separator, which fluid flows downwards to permit the adsorbed components to be desorbed while the fluid left in the bed is forced downwards. Accordingly, simultaneously with the feed of the desorbent fluid, the fluid in the bed is withdrawn from a withdrawal port provided at an appropriate portion downward of the feed port.
  • the positions of feeding the desorbent fluid and withdrawing the fluid are so selected that the withdrawn fluid is rich in desired components. For instance, a method is possible in which a section or a sub-section absorbing one certain component alone is selected, to which the desorbent fluid is fed from upstream of the section while withdrawing the fluid in the bed from downstream of the section.
  • this third step the desorption is conducted so that part of the adsorption bands remain in the bed. This is because the adsorption bands of the respective components formed in the bed in the second step are generally partially superimposed. If these superimposed portions are removed by desorption, the composition of the product ob- tained deteriorates. Another reason is, that the adsorptiont band present in the section into which the starting fluid is fed, is desorbed in the first step, requiring no desorption in the third step.
  • the portion not desorbed during the first step of a subsequent cycle forms one adsorption band together with the adsorption band of the starting fluid which is fed in the first step.
  • the method of the present invention fundamentally comprises the first, second and third step but may be modified in various forms.
  • an auxiliary step in which, when the feeding of the starting fluid is stopped, a desorbent fluid is fed from the feed port for the starting fluid or from a position upstream of the feed port, and simultaneously the fluid running downwards through the bed is withdrawn from a position downstream of the feed port.
  • This auxiliary step is effective, when the starting fluid contains a component which is much harder to adsorb than other components, in withdrawing such component from the bed prior to its movement through the bed in the second step.
  • Fig. 1 shows a fundamental arrangement of an adsorption separator for suitably carrying out the method of the invention.
  • the separator is arranged to include a circulating system which has three unit packed beds (1) to (3) and a circulating pump (5). Each unit packed bed is packed with an adsorbent.
  • the unit packed beds may be of the same or different size.
  • valves (14), (15) and (18), respectively to arbitrarily control the passage of the fluid through the respective unit packed beds.
  • (7) is a starting fluid tank
  • (8) is a tank for the desorbent fluid
  • (9) and (10) are tanks for the withdrawn fluids
  • (6) is a pump for feeding the starting fluid.
  • the valve (14) inhibits the fluid from being discharged into the unit packed bed (2) when said fluid from the unit packed bed (1) is withdrawn from the withdrawal : pipe having the valve (13).
  • the valve (15) prevents the passage of the fluid between the unit packed beds (2) and (3) after introduction of the starting fluid into the unit packed bed (3).
  • the valve (18) is provided to prevent the fluid from passing into the unit packed bed (1) when said fluid is withdrawn from the unit packed bed (3) through the withdrawal pipe having the valve (17) and also prevents the passage of the fluid between the unit packed beds (3) and (1) after introduction of the desorbent fluid into unit packed bed (1). Therefore, some of these valves may be omitted depending on the manner of arranging the connecting these unit packed beds and the manner of connecting the fluid introduction pipes and the fluid withdrawal pipes to the bed-connecting pipes. It is preferred to provide at the upper portion of each bed a means for dispersing the fluid to be introduced into the bed uniformly over the cross section of the bed.
  • Fig. 2 is another embodiment of the adsorption separator useful in the method of the invention.
  • the unit packed bed (3) of the separator of Fig. 1 is divided into two unit packed beds (3) and (4).
  • Two withdrawal pipes are provided for the unit packed bed (4) including the withdrawal pipe having the valve (17) and a withdrawal pipe having a valve (19) which communicates with a reservoir (11) for the fluid withdrawn from this withdrawal pipe.
  • a pipe connecting the unit packed beds (4) and (1) is provided with a valve (21) and is connected with a pipe provided between the unit packed beds (2) and (3) through a pipe having a valve (20). Accordingly, the separator of Fig. 2 allows the fluid passed from the unit packed bed (4) to be withdrawn in two different ways and the desorbent fluid to be directly charged into the unit packed bed (3).
  • Fig. 3 is a further embodiment of an adsorption separator for carrying out the method of the invention.
  • the unit packed bed (3) of the separator of Fig.1 is divided into unit packed beds (3) and (4), between which a valve (22) and two fluid withdrawal pipes are provided, i.e. a pipe having a valve (23) and a pipe having a valve (24).
  • a valve (22) and two fluid withdrawal pipes are provided, i.e. a pipe having a valve (23) and a pipe having a valve (24).
  • the fluid discharged from the unit packed bed (4) can be withdrawn, the withdrawing pipe having the valve (17) as well as from the pipe having the valve (19).
  • the first step is carried out as follows.
  • Valve (16) is opened to feed the starting fluid from the starting fluid reservoir to pass through the unit packed bed (3), and simultaneously valve (17) is opened to withdraw the fluid from the withdrawal pipe in an amount corresponding to the feed.
  • This withdrawn fluid is rich in a component which is hard to adsorb.
  • the feed and withdrawal of the fluid is stopped and the valves (14), (15) and (18) are opened, whereupon the circulating pump (5) is operated to permit the fluid in the apparatus to move from the bed (1) through the bed (2) toward the bed (3).
  • the respective com- ponents in the starting fluid are separated from each other to form the respective adsorption bands in predetermined positions of the bed.
  • FIG. 4A An example of the adsorption bands is shown in Fig. 4A.
  • valve (12) is opened to feed the desorbent fluid from the desorbent reservoir to pass through the unit packed bed (1), and simultaneously valve (13) is opened to withdraw the fluid from the withdrawal pipe in an amount corresponding to the feed.
  • valve (13) is closed and valves (14), (15) and (17) are opened, after which, when feeding in the desorbent fluid, the fluid withdrawn from the unit packed bed (3) is rich in the component which is hard to adsorb.

  • adsorption bands of the easy-to-adsorb component and the hard-to-adsorb component are left behind.

  • the adsorption bands in the apparatus after completion of the first step are as shown in Fig. 4D.
  • the third step may be modified in various ways depending on the form of the adsorption bands in the second step. Especially with the apparatus of Figs.2 and 3, such modification is easy. However, the adsorption bands in the bed should not be completely washed out in either modification for reasons described hereinbefore.
